xbrz problem

No and no.

You can't turn off those performance limitations, not without building your own custom ppsspp version with all of it removed from texture cache, I don't think we'll ever have an option to disable it, through at some distant future it's possible there will be ways to just detect which part of the texture is used and which not, as that would remove the problem all together, so far that's not possible through;p.

Despite common missinformation 3D graphics is usually both lighter and easier to emulate. Which get's especially bad when it comes to ports of older games that weren't optimized for the console we're emulating. Comparing ps1 games to psp ports is completely pointless.

And yeah as mentioned 5xBR shader will only look nice with native games that actually provide full resolution content. xBRZ would also look terrible if it had to take a screenshot of games abusing stretched content as it's input.
